shaped like a horse-shoe; moreover, tlic contiguous stripes 

 ou intervals 8 and \), instead ot" being niucli sliorter than 

 tliat on 7 , are nearly or (juite as long ; and there is no trace 

 of the median stripe on the prouotum. The sides ot" the 

 prothorax are not parallel in the basal half, but distinctly 

 convergent in front.

Described from four specimens. 



Alcidesjngalis, sp. n. (PI. VII. fig. 5.) 



S ? . Form subcylindrical ; integument black, with pale 

 markings formed of small, short, whitish, plumose scales 

 dusted with ochreous powdering ; the prouotum with three 

 stripes, the median one much narrower than the laterals, and 

 all reaching the apex ; the elytra with a broad sutural 

 stripe on intervals 1 and 2 from the base almost to the 

 middle ; a narrow, shorter, and rather oblique stripe start- 

 ing at the base ou interval 6 and ending on interval 4 ; 

 a broad, complete, common, transverse band behind the 

 middle, which widens and curves forwards at the sides, being 

 continued to the base as a narrow stripe along interval 10; 

 and a subtriangular apical patch covering all the declivity 

 except interval 11 ; the lower surface fairly densely covered 

 with plumose scales and ochreous powdering, which are 

 thinner down the middle of the metasternum and abdomen. 



Head unusually broad, longitudinally rugulose, and with- 

 out any median fovea. Rostrum stout, subcylindrical, 

 almost straight, slightly narrowing from the base to the 

 middle, and feebly widening again at the apex, of about equal 

 length in the two sexes, coarsely jjunctate and longitudinally 

 striolate at the base, and with a broad deep furrow on each 

 side between the eye and antenna; the punctures strong and 

 close throughout in the ^ , almost as strong ou the basal 

 half in the ? , but much finer apically. Antennce inserted 

 beyond the middle in both sexes, the scape a little shorter 

 than the funicle, of which joint 1 is longer than 2 and 3, 

 3 to G are bead-like and transverse, and 7 is much shorter 

 than the club. Prothorax a little shorter than its basal 

 width, subcouical, gradually narrowed from base to apex, 

 with the sides only slightly rounded and the subapical con- 

 striction feeble ; the dorsal apical margin rounded, the 

 longitudinal outline almost flat, but the whole prothorax 

 tilted upwards in front ; the dorsum set throughout with 

 small separated granules, those on the discal area each
